Abstract

Un sistema (1000) y un método para detectar y aislar un pulso electromagnético ("EMP") a lo largo de las líneas eléctricas de primera fase (601), segunda fase (602) y tercera fase (603) conectadas en forma eléctrica con una infraestructura monitoreada de manera tal que proteja a la infraestructura monitoreada, el método de detección y aislamiento incluye una unidad de fase que recibe datos de señales eléctricas desde un sensor conectado en forma eléctrica individualmente con cada una de las líneas eléctricas de primera fase (601), segunda fase (602) y tercera fase (603), respectivamente, corriente arriba y asociadas con la infraestructura monitoreada. El método incluye determinar si los datos de señales eléctricas asociados con la respectiva línea eléctrica indica un componente El de un EMP y, si así fuera, accionar un subsistema de aislamiento (507) menor de 500 nanosegundos para aislar en forma eléctrica la respectiva línea de la comunicación eléctrica con la infraestructura monitoreada.
